This page covers gearbox lubrication, temperature alarms, cooling performance, vibration trends, oil analysis, and bearing condition monitoring for the LT-32 fleet.

Overview

SB-LWS-2025-07 amends the gearbox manual lubrication section for affected LT-32 CCV turbines with Fabrikam FGT-3200 gearboxes by changing the gear oil from Proseware PWG 320, ISO VG 320, to Proseware PWG 220, ISO VG 220.1 For affected turbines, the total oil volume remains 410 L, the minimum oil sump temperature before start-up changes to +5 °C, and A2101 and A2102 remain at 75 °C and 82 °C.1 WTG-07 had repeated gearbox over-temperature alarms caused by inadequate oil-cooler heat rejection from reduced fan speed and radiator fouling, with generator-side HSS bearing wear identified as a contributing factor.234567 WTG-07 oil analysis and vibration data show alert-level ferrous wear and HSS bearing vibration above the alarm level, and the bearing replacement remains open until parts are available.891011

Lubrication configuration and operating limits

  • The LT-32 gearbox is a Fabrikam FGT-3200 three-stage gearbox with one planetary stage followed by two parallel helical stages, and it uses splash and forced lubrication with a shaft-driven pump for operation and an electric pump for start-up and flushing.12
  • The lubrication circuit passes oil through a 10 micron inline filter and an air/oil cooler with an electric fan, and a thermostatic valve sends oil through the cooler above 45 °C.12
  • Three immersion heaters rated 3 x 1.5 kW warm the oil sump before a cold start.12
  • Normal gearbox oil sump temperature in operation is 50 to 65 °C, while A2101 is the oil sump temperature warning at 75 °C and A2102 is the oil sump temperature trip at 82 °C.13
  • The current SOP for WTG-01 to WTG-12 applies to LT-32 CCV turbines with Fabrikam FGT-3200 gearboxes and requires converted gearboxes to be topped up only with PWG 220, with residual PWG 320 below 5 % of oil volume.1415

WTG-07 over-temperature and cooler corrective actions

  • Between 2026-04-09 and 2026-06-21, WTG-07 logged 27 A2101 warnings at 75 °C and two A2102 trips at 82 °C, while no other turbine logged an A2101 warning in that period.2
  • SCADA records show WTG-07 raised A2101 and then A2102 on 2026-05-30, and again raised A2101 and then A2102 on 2026-06-19.161718192021
  • The 8D report says the oil overheated because the oil cooler did not reject enough heat at high load, the cooler fan ran at reduced speed, the radiator fins were about 40 % blocked by insects and pollen, and the fan motor bearing had failed.345
  • Corrective actions completed on 2026-06-24 replaced the oil cooler fan motor and cleaned the oil cooler radiator, and verification reported no A2101 warning on WTG-07 since 2026-06-24.222311
  • The maintenance plan added task MP-GBX-07 for all turbines every 6 months to clean the oil cooler radiator and check fan current after INC-2026-006.2425

Oil analysis and bearing condition

  • Oil analysis report TR-OA-2026-0614 is for WTG-07 main gearbox FGT-3200-18-07752, using Proseware PWG 220, ISO VG 220, in service since 2025-10-15.8
  • The WTG-07 sample was reported with overall condition ALERT and action required.8
  • The WTG-07 oil sample had normal viscosity, water, and total acid number results, but iron was 64 ppm, PQ index was 112, and particle count was 20/18/15, each reported with ALERT status where stated.8
  • The oil report says ferrous wear increased sharply since the previous sample and interprets large ferrous particles with normal copper as rolling-element bearing distress rather than gear wear.8
  • The oil report recommends reviewing output-stage bearing vibration trends, inspecting the HSS bearings by endoscope, replacing the filter element, and resampling within 30 days.8
  • For output-stage HSS bearings, the maintenance manual sets velocity RMS limits at 3.5 mm/s alert and 4.5 mm/s alarm, and WTG-07 trend data rose from 2.1 mm/s RMS on 2026-01-05 to 5.7 mm/s RMS on 2026-08-31.262728
  • WTG-02 also has generator-side HSS bearing spalling found by endoscope, and WO-26-0439 is waiting for part FGT-P-22328.2930

Monitoring intervals and alarm responses

  • The maintenance manual sets inspection intervals of 6 months for visual inspection and leak check, 6 months for oil sampling and laboratory analysis, 24 months for endoscope inspection, continuous for vibration monitoring, 12 months for filter element replacement, and as required for oil cooler radiator cleaning.26
  • The 2026 maintenance plan schedules gearbox oil sampling and laboratory analysis every 6 months, oil filter element replacement every 12 months, gearbox oil change every 5 years or on condition, and monthly vibration trend review.31323334
  • For A2101, the manual lists cooling, oil level, load or ambient-temperature, and bearing issues as possible causes, with checks including fan rotation and motor current, radiator cleaning, valve insert LWS-P-30422, oil level, vibration trend, and an oil sample.35
  • For A2102, the turbine stops automatically, the cooling circuit is inspected before restart, and reset is not performed more than once without inspection.35
  • For A2110, possible causes are bearing damage or lubrication starvation, with vibration trend review and endoscope inspection of the bearing as checks.35
  • For A2140, possible causes are a clogged filter element or cold oil, and the action is to replace filter element FGT-P-11872.35

Oil-change and conversion controls

  • The current SOP requires a permit to work, at least two technicians, no lone working in the nacelle, and isolation according to SOP-LOTO-001 before the oil circuit is opened.3637
  • Hot-oil controls require chemical gloves, a face shield, long sleeves, and draining only between 40 and 60 °C, with a spill kit ready at the gearbox and absorbent pads under every connection.3839
  • Each oil change under the current SOP requires 470 L of Proseware PWG 220, made up of 60 L for flushing and 410 L for filling, plus one FGT-P-11872 oil filter element.4041
  • The current SOP drains the gearbox sump and cooling and filter circuit, replaces filter element FGT-P-11872, flushes with 60 L of PWG 220 while running the electric oil pump for 30 minutes, and fills with 410 L of Proseware PWG 220 through a 10 micron filter cart.42434445
  • After filling, the electric oil pump is run for 15 minutes, connections are checked for leaks, the oil level is checked after 20 minutes of standstill, GBX_TMIN_START is set to 5 °C, and the filler is labelled PWG 220.464748
  • A reference oil sample is taken after 24 hours of operation, quantities and batch numbers are recorded in the work order, and the completion form is sent to Litware Wind Systems within 30 days.4950

Spares and open bearing work

  • WO-26-0412 for WTG-07 is waiting for parts to replace the generator-side HSS bearing FGT-P-22328, and the work order remarks that vibration is above the 4.5 mm/s alarm level.51
  • The 2026-07-21 stock snapshot lists FGT-P-22328 as a critical item below minimum stock, with 0 on hand, a minimum of 1, and 2 on order under PO-76994 with expected delivery on 2026-09-25.5253
  • A supplier note says the two FGT-P-22328 HSS bearings under PO-76994 cannot be delivered in calendar week 39 and gives a new confirmed delivery window of 2026-09-28 to 2026-10-02.54
  • The oil cooler fan motor LWS-P-30418 is also listed as a critical item below minimum stock, with 1 on hand, a minimum of 2, and 2 on order under PO-77102 for expected delivery on 2026-08-14.5255

Resolution policy: When two current sources disagree, the source with the higher document-type authority wins (environmental permit 10; service bulletin and grid instruction 9; maintenance manual and management of change 8; procedures, laboratory and inspection reports 7). With equal authority the more recent source wins. A service bulletin that amends a manual section for some turbines is shown next to the manual value, with the turbines it applies to.
